Abstract

The invention discloses a testing device for measuring optical indexes of a display screen at different angles. The testing device comprises a base, stand columns fixed to the base, and a mounting base arranged on the stand columns. Baffles arranged in the vertical direction are fixed to the left end and the right end of the mounting base correspondingly. The baffles are rotatably arranged on thestand columns respectively, so that the mounting base can turn over in the vertical plane, a fixing pin is arranged on each baffle in a sliding mode, and the display screen located in the mounting base can be clamped by sliding the fixing pins. The problems that a traditional testing device is not easy to control the rotation angle, inconvenient to operate, long in consumed time and inconvenient to carry for external field joint debugging are solved.

Description

technical field [0001] The invention relates to the field of display screen detection, in particular to a testing device for measuring optical indexes of a display screen at different angles. Background technique [0002] With the widespread application of airborne head-up displays, more requirements are put forward for the optical indicators in digital image sources. In digital image sources, the brightness and contrast in optical indicators are the most concerned. Different models have different requirements for the display viewing angle of the digital image source, which leads to different brightness and contrast in the optical indicators in different viewing angle ranges. After the digital image source is assembled, it is necessary to test the brightness and contrast of its specified viewing angle. To use specific professional equipment for measurement, the product needs to be fixed on the test equipment. Although the operation is flexible in the test of the specified ...
